To all whom t may concern,.-

Beit known that I, WELLINGTON WILSON, of Bay City, in the county of Bayand State of Michigan, have'invented new and useful Improvements inStovepipe Attachments, of which the following is a full, clear, andexact description.

This invention relates to means for attaching stove pipes to chimneys,also which may serve to hold in place the us'ual'slip collar on thestove pipe that closes the marginal portion of the opening in thechimney wall through which said pipe enters.

The invention consists in a device or attachment of novel constructionfor such purpose or purposes, substantially as hereinafter described andpointed out in ythe claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters ofk reference indicatecorresponding parts in all the figures.

Figure 1 representsa longitudinalsectional elevation of the chimney en'dportionor section of a stove pipe, and sectional view of the chimney, inpart, into which said pipe is fitted, together with a longitudinal viewof my improved stove pipe attachment applied. Fig. 2 is an upperlongitudinal view of said stove pipe piece or section removed from thechimney and with the improved attachment in place on the stove pipe.Fig. 3 is a top viewT of said attachment detached from the pipe; andFig. fl is a broken plan view of a stove pipe, showing a slightmodification in the construction and arrangement of one of the detailsof the attachment.

A indicates a piece of stove pipe the one end of which is designed toenter a hole in the wall B of the chimney B', and C is the usual slipcollar that tits over the pipe A, to close the marginal portion of thehole in the chimney wall through which said pipe enters,

and to give a finish to the stove pipe connec-` tion with the chimney.

D is the stove pipe attachment which holds said pipe to its place in thechimney, and which may also hold the slip collar C in place. Thisattachment, it is preferred to arrange, for convenience sake, 0n the topof the stove pipe A, but it might be on any other side thereof. Itvirtually consists of a longitudinal piece of spring wire anchored tothepipe and constructed to form, by a coil or otherwise, a spring d, at itsinner end which may partly lie Within the pipe, and terminates in aspring armor branch d', project-ing upward orlaterally from and outsideof the pipe at the'inner end of the latter, to spring out andbearagainst the inside surface of the chimney Wall B when the pipe is inplace. Itis also constructed With a loop or spring coilf, at its outerend terminating in a springarm or branch f', which when the pipe is inplace serves to bear against the slip collar C to hold itin place. Theloop or spring coilfserves to receive the head or loop end of a spike G,to anchor the attaching device to the stove pipe A. The point of thesaid spike may either be pressed or projected into the body of the pipe,and bent more or less, as shown in Fig. l, or the point may be insertedbetween the edges of t-he pipe, at the seam, as shown in Fig. 4. Theanchor G is separate from the main wire or part D vand its loop g,embraces the coilf and is free to 'swiugthereom and this connectionleaves theanchor no tendency to release itself from the pipe when driveninto the same and permits it to be readily disengaged from the pipe (bythe insertion of any convenient tool or device), as theanchor will risebodily instead of being bent from its point of connection whichwould'offer more resistance.

It will be observed that the spring coils d and f are disposed, at rightangles to each other, and that the inner coil d is substantiallyparallel with the longitudinal axis of the pipe thereby receiving theinnerend of the pipe between the coil and the main length of wire D. Thecoil f with the returned arm f has a spring action from its connectionwith the said coil f', and the arm thereby is self adjusting to thethickness of the chimney and the extent of this adjustment is limitedonly by the length of this arm. The end spring or arm d at the inner endof the pipe is pulled over on top or outside of the inner end of thepipe toenter the hole in the chimney wall B which said end of the pipeenters, the small spike or anchor G at the other end of the fasteningbeing driven through the pipe. After this has been done', the slipcollar C is passed on and over the pipe and `the pipe with itsattachment driven into the wall B of the chimney. This will, as soon IOOas the spring arm d has been driven into the chimney in fitting the pipeto its place, 4cause said spring or arm d to spring outward and assumean upright or lateral position on the inside surface of the chimney wallB, to lock or hold the inner end of the pipe thoroughly fast. During thelatter part of the inward movement of the pipe and its attachment, thecollar C having contacted with the chimney will be arrested, and as thepipe is forced inward the spring arm f will yield until the inner arm dcan spring upward, and thereby the said inner spring arm will engage theinner surface of the wall while the outer spring arm f will pressforward against the collar C, so that no vibration will allow the pipeto work out of the chimney or out of place until, when required, thespike or anchor Gr is'lifted out of the pipe, which is necessary to bedone to enable the pipe to be drawn out of the chimney. i

With this chimney and stove pipe attachment, as 'shown and described, nospecially constructed pipe is necessary and it is adapted to allchimneys. It is not liable to get out of order and its cost is small,both to the trade and public, while its little bulk and weight makes theexpense of shipment inconsiderable. It is also so simple in adjustmentthat even an inexperienced person or child, able to give a light blow onthe spike or anchor, will be competent to adjust it and make it firm tothe pipe. It also prevents the pipe from being put too far into thechimney.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. As a new article of manufacture, a stove pipeattachment, consistingr of an elongated main member or body having atlits inner end a spring coil and an arm projecting from said coil, thecoil serving to receive the inner end of a pipe between itself and themain length or body and serving also to give the spring action to thearm, and a returned spring arm on the outer end of the main member, theattachment further having a fastening device at its outer end forfastening the same to the stove-pipe substantially as described.

2. As a new article of manufacture, a stove pipe attachment, consistingof an elongated main member or body having a laterally projecting springarm at its inner end, a spring coil at its outer end and a returnedspring arm extending from said coil, said arm being yielding fromitsconnection with the coil for adjusting itself to the thickness of achimney wall, the attachmentfurther having a fastening device at itsouter end for fastening the same to the stovepipe substantially asdescribed.

3. As a new article of manufacture, a stove pipe attachment consistingof an elongated member or body having a spring arm at its inner end, aspring coil at its outer end an arm returned on the main member fromsaid coil and yielding from its connection with the latter, and aseparate anchor having a loop loosely embracing such outer coil to movethereon, the free end of the anchor having a bent, pointed termination,substantially as described.
